Application filed May 23,1904. Renewed July 21,1906. Serial No. 327.213.

- certain amount-of 000 ng, impurities have c'ollected in the cans whichit is desired to discharge by means of the interior pressure gen eratedwithin the cans.

The present machine is designed to mechanically and thoroughly'performthe sevk eral operations here indicated or im liedviz. t e wiping ofthecan cap or hea previously to soldering, the deposit of the flux andsolderin the required amounts. and at ,the pro er place, the heating andcleaning of the sol ering-tool, and adequate fusing to stop off the holeinthe cap or head either as a temporary or final step, and hermeticallysealing the can. In the discharge of these functions the machine isproperly a vent-hole-solder ing or stop-off machine, which it isordinarily called,-and at the same time it is .peculiarly adapted tounstop the can after the first cooking of its contents, so as to freethem of impurities, as before stated. I

Referring to the accompanying drawings,

Figure 1 is a plan view of my apparatus. Fig

2 isan elevation. Fig. 3 is a partial plan of the can by which theclosing implement is actuated. Fig. 4 is a side elevation of the same.Figs. 5,- 6, 7, 8, and 9 are vivws of cam-pocket plates. Figs. 10 and 11are elevations taken at right angles with each other,

showing the wiper for cleaning the solderingiron. Fig. 12 we sectionalview of the sol der-pot.

The machine comprises a suitable support-- ing frame or standard A, andI have'here shown two other standards A su'fiicientl separated to carrythe pulleys 2, about which an endless traveling belt 3 ismovable andupon which belt the cansgi arepllaced and from which they aredeliveredtoe entering end of the machine. The belt'ext'ends be- 'tion, as shown at7.

yond the machine,and that end serves to receive and discharge the cansafter they have passed through the machine.

The operative parts of the a paratusare' carried upon a disk 5, which iss own as sup- ,ported upon the central standard A; but it will beunderstood thatany other suitable form of 'bed or en port maybesubstituted for standards A an A herein shown. The upper surface ofthis-disk 5 may be channeled at one side of the center and in the lineof travel of the belt 3, so I that while the belt passes through thechannel and across the disk the surface of the belt will be in suchposition that the cans standing thereon on end and with thevent-openings upward may b'e-delivered from the belt upon the disk or asuitable track carried thereby and moved around the disk while thesealing operation takes place, as will be presently described.

Power may be applied to this apparatus through a horizontal shaft 6,extending beneath the disk 5 and having a pulley or other equivalentmeans for applying a rotative mo- A vertical shaft 9 is fixed instandard A, and the revoluble carrier table-or spider 10 has abevel-gear 8 fixed to it, so as to be driven by a bevel-pinion fixed tothe power-shaft 6.

The spider 10 has its periphery irregularly formed and adapted toreceive plates 11, which are fixed thereto by means of bolts passingthrough slotted openings 12, which openings enable the operator toadjust the pocket-plates, as may be required. The plates have verticalflanges 13, and they may e made of any desired curvature, so as to fitdifferent sizes of cans. Thus by the use of these pocket-plates it willbe seen that any sized cans may be operated upon by this ma chine bysimply adjusting or replacing these pocket-plates.

Upon each side of the carrying-belt are guideways 14, and these aresupported upon slotted brackets, as at 15, adjustable bothhorizontallyand vertically, the first adjustment'serving to move the guideways tore-' ceive-cans of larger or smaller diameter, and the vertical adjustments in like manner raise or lower the guideways for longer orshorter cans. At the point where the guideways ap- IOO c eanslngdevices.

proachthe revolving spider there is a hinged spring-pressed gate 16,forming a continuation of the inner guideway and adapted to yield aseach cah passesit and enters one of the ockets, so. as to be received bythe vertica ly-curved fiange13, and as the spider is constantlyrevolving in a horizontal plane it successively removes the cans fromthe car rying-belt and transports them around the perTiphery of thedisk.

e cans are maintained in their position during their travel around thedisk by a circular guideway 17, against which the exterior of the canstravels, while the-interior portionfits within the pockets, aspreviously described. As each can'commences its travel around the circlethe top of the can and vento ening pass beneath one or more wipers or Inthe resent case I have shown a single device 0 this sort at 18, and thisdevice may carry any soft, porous, oQfiexible material which is not onlycapable of. sufficiently brushing and cleansing the vent-opening, but italso appliesan acid to the opening, so as to prepare it for thereception of the-solder.

The solder may be applied either in the form of awire and fed to thepoint of use by suitable mechanical means, or it may be contained withina solder-pot 19 and maintained in a melted condition by a jet or burner19, the heat fromv which passes through a chame ber 20 beneath thesolder-pot and thence escapes up the sides of the pot, thus maintainingthe-solder always in a molten condition.

This pot is sup orted, as plainly shown in Fig. 2, in line a ove thetraveling cans-and in such a position that the soldering or sealingirons or implements 21 may be first dipped into the solder, then raisedout-of it, and applied to the vents-of the cans as they pass eyond thesolder-pot. These solder irons or implements 21 maybe made in anysuitable or well-known manner .and are here shown as supported upon arms22, wlnch are fulcrumed ,in standards at 23. The inner ends of the armsproject beyond the fulcrumpoints 24 ends25.

ings of. the cans.

- '26 represents a fixedannular channel suitably supported upon the post9 and having its upper and lower flanges separated at such a distancethat the ends 25 of the soldering 'im' lement may travel freely in thesechanandcarry ball or other suitableciently to pass the ede of thesolder-pot. 6:;

Then the curvature of t e cam will by its action upon the stem or handledepress the iron into the solder-pot, so that it will take up a ortionof the solder. Then it will be raise so as to pass over the rim orperiphery of the solder-pot, and the next curvature of the cam willdepress the iron and bring it into contact with the vent-opening, WhlCh,

' having been cleansed and prepared with acid,

as previously described, will then be in condition to receive the solderand be closed. It

will be seen that the soldering implement and the cans travel toajconsiderable distance after leaving the'solderin'g-pot, and -theimplement remaining in contact with the vent insures the thorough closinthereof before the cans reach the point 0 discharge. At any desiredpoint before the discharge. is reached the cam-grooves 27 act to againraise the soldering implements, thus leaving the cans free, and whenthey reach the point of discharge the cans are received by curved guides14 and these guides transfer them from the pockets of the spider uponthe traveling belt 3, Whereit emerges after crossing the disk, and thecans are then delivered at the opposite end of the machine from theirpoint of reception.

The traveling b lt is moved by a sprocket 28, fixed. upon the end of theshaft which carries one of thedrums 2; and a chain connecting thissprocket with a similar sprocket upon the main shaft 6 serves totransmitmotion.

It will be understood thatthe solderingirons may be depressed upon thecans, or the cans may be raised into contact with the solderin -irons,or both operations may be .effecte I have here shown a track 29,extending in the line of travel of the cans from the point Where theyare to be brought into contact with the soldering implement, and thistrack is beveled so as to rise from the surface of the disk 5 upon whichthe cans are being carried, thus raising the cans-slightly and retainingthem in this raised position while in contact with the solderingimplement. The

employment of these tracks also reduces the frictional resistanceencountered inmoving the can over a flat surface.

In order to maintain the soldering implement 'at a proper temperature, Ihave showna-closed segmental, chamber 30, which extends a sufficientdistance around the -periphe'ry of the apparatus'and is-open at the endsand also inclined'at such an angle that when the cams 27 have raised thesoldering implements after they have completed their task they willthereafter be carried in 'sucha plane that they will enter the chamber30, which also has an open slotat the top, so

that the shanks of the irons can pass through this slot; Within thechamber may be fixed burners or any suitable formof heater 30,-

so that the temperature of the implements may be raised to any desireddegree. After leaving the chamber it is desirable that the ends of theimplements be cleansed so that they properly perform their work. Forthis purpose I'have shown wipers 31, which may be made'of any suitableflexible porous or absorbent material and are supported in such positionthat'as the implements approach they will contact with thesewipers andbe cleansed, and, if desired, acid or a flux may also be applied to theirons. As shown in F'gs. 10 and 11, these wipers are supported uponhinged arms 32, and these armsand the wipers are maintained in a normalposition in .re'adiness for the, contact of the implement by springs 33,which springs yield to allow the implement to pass and immediatelyreturn the wiper to its normal position.

The cam plate or disk 26 is secured to the vertical shaft 9 by key,set-screw, or other.

device, so that it may be raised or depressed,

and the standards 23, upon which the solder- 1 ing implements arecarried, may be provided with holes or otherwise constructed so that theimplements can correspondinglybe raised or depressed to suitdifierent'heights of cans upon which they are to operate.

In another application for apatent of even date herewith and forasimilar purpose I have described and claimed mechanism by which wiresolder may be suitably delivered to be applied to the vents by theheated-implel'nents, and the same or similar mechanism may also be usedin the present-apparatus, as shown in Figs. 3 and 4, without departingfrom the essential features and character of my machine.
